| |
ARP monitoring does not work when we have a network in the following configuration:
eth0----+ +----bond0.100----br0-100---{+virtual machines | | +----bond0----+----br0---(fixed IP)->--{LAN arp_ip_target} | | eth1----+ +----bond0.200----br0-200---{+virtual machines
This patch extends bond_arp_send_all to check if a device is also in a bridge.
This is related to the following issues: http://launchpad.net/bugs/736226 http://bugzilla.kernel.org/show_bug.cgi?id=31822
Thanks to help from Andy Gospodarek <andy@greyhouse.net>.
